Typically most factory stock cars have what are called "in tank" fuel pumps. This means that the fuel pump it self is INSIDE the fuel tank. In order to get to it you need to drain (or just use up by driving) the fuel in your gas tank and then gain access to it. There should be a hatch which allows access to the inside of the fuel tank for just this reason. As for the exact location of the fuel tank and how to access it, you will need to do more research on this specific vehicle.
Also be VERY careful if you do this your self. Any sparks or even static electricity may cause a fire due to left over gasoline or (more probably) the vapors from said fuel.
